The aim was to evaluate the accuracy of BI-RADS categories 3 - 5 in breast ultrasound (US) as the first-line imaging method.
5077 examinations of a consecutive, unselected and mixed collective of symptomatic and asymptomatic patients were performed. Of these examinations, 835 cases of BIRADS 3 - 5 could be analyzed.
The PPV with respect to a malignant lesion for BI-RADS 3, 4, 5 was 0.03, 0.48, and 0.97, respectively. When BI-RADS 4 and 5 cases are considered to be suspicious, the ratio of benign to malignant findings corresponds to 1:1.8. Analyzing BIRADS 3 - 5 lesions, the sensitivity, specificity and accuracy are 0.92, 0.85, and 0.87, respectively.
The data support the feasibility of US for discriminating malignant from benign findings corresponding to the ACR BI-RADS classification without excessively increasing the number of unnecessary biopsies.
评估 BI-RADS 类别 3-5 在乳腺超声（US）作为一线成像方法的准确性。
对连续、非选择性和混合的有症状和无症状患者进行了 5077 次检查。其中，835 例 BIRADS 3-5 病例可进行分析。
对于 BI-RADS 3、4、5 的恶性病变，PPV 分别为 0.03、0.48 和 0.97。当 BI-RADS 4 和 5 病例被认为是可疑时，良性与恶性发现的比例为 1:1.8。分析 BIRADS 3-5 病变时，敏感性、特异性和准确性分别为 0.92、0.85 和 0.87。
这些数据支持在不增加过多不必要活检的情况下，使用 US 根据 ACR BI-RADS 分类区分良恶性病变的可行性。
